FIELD OF INVENTION

This application relates to a diverter valve with integral, atmospheric type vacuum breaker and inlet and outlet check valves which finds particular application to deck mounted installations such as a roman tub.

BACKGROUND OF THE INVENTION

Back flow preventers are used in commercial and household installations, for example, bidets, Roman tubs, barber shop and hairdressing salon fixtures, laboratory sinks, food processing facilities, chemical manufacturing, metal plating facilities, just to name a few, to prevent the contamination of the potable water supply. The water in each case is used in different manners and the installation of back flow preventers and check valves would be required for each use to protect the water supply from contamination or a separate back flow preventer and check valve would be installed in the line in advance of the components in the system. For example, in a bidet, the water is diverted to the rim or the spray. In a soaking or whirlpool bath tub the water is diverted to the spout, shower head or removable handheld shower. A number of proposals have been made for the diversion of fluids. Various methods and devices have been used to protect the potable water system from contamination. The premises may be isolated to protect the purveyor's water distribution system by installing a back flow preventer at the water line into the building. An area may be isolated when a portion of the building has toxic material used there. That portion of the building should be isolated by installing a back flow preventer so as to protect the individual using the water within the building. Finally one may individually isolate each fixture or piece of equipment from the water system such as is the case in Applicant's own structure described in Canadian Patent 1,225,006 which provides back flow prevention, in a compact, easily manufactured, effective unit. The present invention describes improvements thereto by adding a plurality of checking devices and improves the structure and repair of the diverting valve.

It is therefore an object of this invention, to provide a diverter valve with, integral atmospheric type vacuum breaker and inlet and outlet check valves in an integral structure which is entirely reliable and easily serviced.

Further and other objects of the invention will be realized by those skilled in the art from the following summary of the invention and detailed description of preferred embodiments thereof.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

Similarly as taught in my Canadian Patent 1,225006 there is illustrated a Diverter Valve 10 which is installed on for example a deck D for a roman tub to receive hot and cold water from valve mechanisms 5 and 6 which provide hot or cold water and variations of the flow and mixtures thereof to the diverting valve 10. For this example valve 5 will supply hot water and valve 6 will supply cold water. Therefore the supply tubing 1 and 2 are providing cold water into the bottom of faucet valve 6 and hot water into the bottom of faucet valve 5. Cold and hot water are therefore inlet to the bottom of the Diverting Valve 10 via tubes 3 and 4 and fitting 8 to inlet coupling 8a and inlet 26 of the housing 20 of the Diverting Valve 10. By rotating the handle 20a of the housing 20 the user may select with this embodiment one of three positions; a spout to the tub(not shown), a fixed wall shower head (not shown), a supply tubing 7 extending to a hand held shower unit, (also not shown). Alternatively any other alternative fixtures may be provided for which back flow prevention is desired.

Referring now to FIGS. 2 and 3 there is illustrated the installation of the components of the handle and the assembly of the trim for the valve and the components of the valve. Therefore there is provided a control handle 20a attached to the Diverting stem 30 having an engaging portion 31 which engages with the opening proximate the bottom of the handle portion 20a as shown. The handle portion 20a includes venting portions 20f to allow the valve to vent to atmosphere when not in operation. To enable this to occur a float 50 is provided which is moved from a position as illustrated closing the inlet tube 42 of the stationary body sleeve 40 of the valve assembly to a position closing the vent 32b of the valve assembly thereby allowing water into the chamber 48. The Diverting stem 30 therefore is moveable within the stationary body sleeve 40 which are held together as an integral package by a retaining ring 70 as best seen in FIGS. 4, 4a, and 4b. A trim portion 20d extends down to flange portion 21a covering thereover via flange portion 20e to provide the proper trim for the Diverting valve 10. Integral with the handle portion is a downwardly depending skirt 20c which covers the diverting stem 20 and provides for a venting chamber 20f and 20g which vents the cartridge via the windows 32a through the passage 20g, 20f, and 20b out to atmosphere thereby providing a vacuum breaking path. This path of course is closed by the top of float 50 via the movement and sealing of the float 50 in relation to the above mentioned passage as will be described here in after.

The inlet tube 42 therefore is provided with a one way check mechanism 60 proximate the top thereof which is located at a predetermined position below the top end 32a of the inlet tube to allow proper functioning of the float mechanism 50 and to provide checking of the fluid flowing from the top of tube 42 to the passage 48 between the tube 42 and the inner wall 40d of the stationary sleeve 40. Therefore the fluid will pass one way down into the chamber 48 but will not pass back from the chamber 48 back into the inlet tube 42 thereby providing a check mechanism and protection for the inlet water.

Referring now the FIGS. 4, 4a, and 4b there is illustrated the cartridge 10a of the Diverter Valve 10 comprising the moveable Diverting Stem 30 moveable within the stationary body sleeve 40 and being retained together by retaining portion 70 having locking portions 73b and 73a which engage with tabs 43a and 43b respectively of the body sleeve as best seen in FIG. 5 and 5a. The locking ring, as best seen in FIG. 9, and FIGS. 9a through 9f, includes an opening portion 70a to allow the locking ring to rest on the flange 41 of the stationary body sleeve 40 under the flange portion 72 after the opening 70a allows passage of detent 34 through said opening 70a during assembly thus allowing the bottom of flange 72 to rest on flange 41. The opening 73b will engage with the tab portion 43b and the opening 73a will engage with the tab portion 43a.

An opening 32a provided proximate the top of stem 30 allows venting of the valve as described in relations to FIGS. 2 and 3. The stem 30 therefore is moveable within the body 40 within the limits of the detent 34 and the locking ring 70 as provided by stops 71b an 71a. These positions therefore provide a full range of selectivity from the openings 44 and the single opening 45. The openings 44 are provided for shower outlets and have reduced volume in relation to opening 45 which includes the reinforcing bar 45a to retain the seal from collapsing into the opening 45 as best seen in FIG. 6a or from sliding through the opening 45 when the Diverting valve is operated. Typically the opening 45 would lead to the spout for the Roman tub whereas the multiplicity of openings 44a would lead to a shower or a telephone shower. A unique check valve 44b is provided, as best seen in FIGS. 12 and 12a, which seats in the seating provided around the opening 44a via the ring 44b(1) provided with the gasket 44b. When water comes out of opening 44a it will pass through opening 44b(3) of the check valve 44b. However any water attempting to backup into the outlet will be prevented by the occluded face 44b(2) of the one way check valve provided. As best seen in FIG. 6a a single outlet is provided from the Diverting stem which is typically sealed by an "O" ring 35a. Therefore this single outlet is aligned selectively with the outlets 25, 27 or 28 when water is inlet into the valve through inlet 26.

Referring to FIGS. 5 and 5a the stationary body sleeve is illustrated having an inlet tube integral therewith at 42 having a top at 42a and a check receiving portion 42b wherein the check 60 is positioned as best seen in FIG. 6a. The stationary body 40 therefore has an outer diameter 40c an inner diameter 40d a gasket receiving portion 40a, and an opening 44, 45 and 46 as previously described. The inlet tube has an inner diameter 46a an outer diameter 46b. The inner diameter 40d of the outer body 40 and the outer diameter 46b of the inlet 42 defines a chamber 48a where water will pass from the outlet 42a of the inlet tube to the chamber passing the check valve 60 (but not passing back to the inlet tube) and then selectively out of one of the openings 44 or 45 and 28, 27, or 25 of the housing 20. This can be best seen in relation to FIGS. 7, 7a and 7b and the reader is referred to these figures in relations to the aforementioned paragraph.

Referring now to FIGS. 6 and 6a the entire assembly is illustrated in cross section with the stem 30 selecting the outlet 28 and the outlet 45 and therefore sending the water to the spout. The water will pass up the inlet tube to opening 6a, overflow by raising the vacuum breaker 50 so that portion 50a engages with opening 32b, sized to receive the flange or cylinder size 50a thereby closing the valve to atmosphere via the seal 52a raised against the bottom of the opening 32b thereby sealing the diverting valve from atmosphere and allowing water to pass over into the chamber 48a and selectively out of the valve. When a shower is selected typically there is a head of water retained in the shower feed pipe or telephone tubing. Since the telephone tubing is not always within the tub in a Roman tub it is preferred to prevent any dripping from the telephone shower onto for example the floor. Therefore a check valve is provided proximate the outlet as well to prevent water from passing fluid back into the valve from the telephone shower or the shower nozzle. As described in relation to FIGS. 12, 12a and FIG. 5a the vacuum breaker in essence works identically with the previously described vacuum breaker of my previous Canadian Patent 1,225,006 with the exception of enhanced features of the float and the plug 51 providing a much tighter package. When water is shut off therefore from entering the valve the Diverter Valve float 51 will close the end of the inlet tube 42a and therefore allow the passage of air into the valve and thereby preventing creation of a vacuum in the valve with all the known problems that this may create.

FIGS. 9 through 9f describe the retaining ring as previously described with all of the components thereof including an opening 70a and detents 71a and 71b, and detents 73a and 73b which engage with the cartridge as previously described.

Referring to FIGS. 10-10b there is described the unique check device provided as best seen in FIG. 6a which includes a substantially flexible material have a shape substantially shown having a tapering bottom portion 61 and a substantially more biased tapered form 60a and a substantially cylindrical section 62 which butts up against the detent portion 42b of the inlet tube 42. The slanting surfaces 60 and 61 therefore provide the checking and tight fit. The inner diameter of the moveable diverting stem 30 and the inlet tube providing an inlet chamber 48 by preventing the passage of the fluid back from the passage 48 to the inlet tube 42.

Referring to FIG. 11 there is described the float mechanism 50 having a tapered wall 50a in order to shut off the venting of the valve as previously described in cooperation with the seal 53 and shut off the top of the inlet tube via stop 51 and downwardly depending skirts 52. The float of course is sized to fit within the portions of the inlet tube at 54 and breather opening 42b at 50a.

Referring to FIGS. 12 and 12a as previously described there is provided the unique check mechanism 4 and 4b which retains in the opening 44 as best seen in FIG. 4b so that the face 44b(2) will prevent any fluid from re-entering the opening 44a but the opening 44b(3) will allow passage of the fluid from opening 44a to the selected outlet. It is recommended that the material for both the checks of FIGS. 10 and 12 be made from epdm 60 duro.

As many changes can be made to the preferred embodiments of the invention without departing from the scope of the invention; it is intended that all material contained herein be interpreted as illustrative of the invention and not in limiting sense.

The diverting valve of claim 1 or 2 wherein the check for the inlet tube further comprising a resilient member tapering outwardly away from the inlet tube toward the inner wall of the moveable stem thereby allowing flow from the inlet tube to the chamber yet preventing flow from the chamber into the open end of the inlet tube.
 16. The diverting valve of claim 1 or 2 wherein the single opening of the stem is provided with a seat for a seal surrounding the opening.
 17. The diverting valve of claim 1 or 2 wherein the moveable stem further comprises a tube having an outer surface whose dimensions correspond substantially to the inner stem surface dimensions of the inner wall of the body sleeve defining the chamber and providing an intimate close tolerance fit therebetween yet allowing movement of the stem within the body sleeve.
 18. A diverter valve with integral vacuum breaker back flow preventer and inlet and outlet check valves comprising a housing having two ends, one end for receiving a valve cartridge in use, the housing having an outer wall and an inner wall, the inner wall defining an opening extending from proximate one end to proximate the other end of the housing, the housing having an inlet port, the housing having at least two outlet ports; a stationary body sleeve having a first end and a second end and an inner and outer wall defining a sleeve opening, the second end of the body sleeve for insertion within the housing opening to proximate the inlet port in use, the body sleeve having an inlet within the sleeve opening in communication with the inlet port of the housing and extending a predetermined distance in the sleeve opening from the inlet port of the housing towards the cartridge receiving end of the housing to an open end, the inlet port having in communication therewith a check to allow flow from the inlet port but not back to the inlet port, the body sleeve having disposed therewith openings extending from the sleeve opening to the outer wall of the body sleeve and in direct communication with the at least two outlet ports of the housing, some of the openings of the body sleeve having been provided with a check which precludes reversal of flow into the valve; a moveable diverting stem having a first open end and a second vented end wherein a handle is disposed in use and having an inner and outer wall, the first and second ends of the moveable stem providing therebetween a hollow stem chamber wherein is disposed the waterway in use, said hollow stem chamber having an open end disposed at one end thereof and being the first end of the diverting stem and for insertion within the sleeve opening of the stationary body sleeve to proximate the inlet port of the housing, the diverting stem having disposed proximate the first end a single opening for selected communication with the openings of the stationary body sleeve; a closure moveable from a position spaced from the open end of the stem chamber closing the upper end of the diverter valve to the atmosphere, to a position closing the stem chamber of the diverter valve to atmosphere, whereby when fluid is fed through the valve the closure is moved away from the open end of the stem chamber closing the valve to atmosphere to permit the fluid to pass into the valve, and when fluid is not passed through the stem chamber, the closure opens the open end of the stem chamber to atmosphere and vents the valve to atmosphere, wherein when assembled the stem may be selectively moved to communicate the single opening of the stem with the openings of the stationary body sleeve and fluid will flow to the selected outlet port of the housing.
